Dynamics of agt vehicles with single-axle bogies

摘要

The steering type of a mechanical guidance system has been used for Automated Guideway Transit (AGT) system in Japan. Recently, the single-axle bogie system has developed for AGT vehicle and applied to actual vehicles. This paper describes dynamic characteristics of AGT vehicle with single-axle bogies. Introducing a nonlinear, 17 degree-of-freedom dynamic model, a computer simulation study on the lateral motion of the AGT vehicle with single-axle bogies are carried out. In order to show the dynamic characteristics of the single-axle bogie clearly, it is compared to that of the AGT vehicel with conventional steering system. The simulation study with actual vehicle parameters shows that single-axle bogie has suitable characteristics for AGT system. The simulation with multibody dynamics software is also shown to demonstrate the AGT vehicle with single-axle bogies in realistic situation.
